When a program does not need the data space any more, it should free the virtual storage and remove the entry from the access list. The required parameter on the DSPSERV DELETE macro specifies the STOKEN of the data space to be deleted. A problem-state program with PSW key 8 - F must be the owner or creator of the data space and have a PSW key that matches the storage key of the data space.
